MethodBase.IsPublic 屬性
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
取得值,指出這是否為公用的方法。
public:
property bool IsPublic { bool get(); };
C#
public bool IsPublic { get; }
member this.IsPublic : bool
Public ReadOnly Property IsPublic As Boolean
如果這個方法是公用的,則為 true
,否則為 false
。
下列範例會 IsPublic 使用 屬性來顯示訊息,指出指定的方法是否為公用。
int main()
{
Console::WriteLine( "\nReflection.MethodBase" );
//Get the MethodBase of a method.
//Get the type
Type^ MyType = Type::GetType( "System.MulticastDelegate" );
//Get and display the method
MethodBase^ Mymethodbase = MyType->GetMethod( "RemoveImpl", static_cast<BindingFlags>(BindingFlags::NonPublic | BindingFlags::Instance) );
Console::Write( "\nMymethodbase = {0}", Mymethodbase );
bool Myispublic = Mymethodbase->IsPublic;
if ( Myispublic )
Console::Write( "\nMymethodbase is a public method" );
else
Console::Write( "\nMymethodbase is not a public method" );
return 0;
}
/*
Produces the following output
Reflection.MethodBase
Mymethodbase = System.Delegate RemoveImpl (System.Delegate)
Mymethodbase is not a public method
*/
C#
class methodbase
{
public static int Main(string[] args)
{
Console.WriteLine("\nReflection.MethodBase");
//Get the MethodBase of a method.
//Get the type

Console.Write ("\nMymethodbase is a public method");
else
Console.Write ("\nMymethodbase is not a public method");
return 0;
}
}
/*

' Mymethodbase is not a public method
若要取得 MethodBase,請先取得類型。 從類型取得 方法。 從方法取得 MethodBase
。
MethodBase
如果 或 建構函式不是公用,則會受到保護,而且無法立即存取。 若要存取非公用方法,請在 中GetMethod
將BindingFlags遮罩設定為 NonPublic
。
